Anodising is an electrochemical process which converts the metal surface into a decorative, durable, corrosion-resistant, wear-resistant oxide layer. This aluminium oxide is not applied to the surface like coating or plating, but is fully integrated with the underlying aluminium substrate. This means it cannot chip or peel. It has a highly ordered, porous structure which allows secondary processes such as colouring.

Naturel anodising

Our anodising layers meet all the quality standards for outdoor use, such as QUALANOD and BS. Alumet has special printing equipment installed to print dates and production numbers on aluminium profiles in order to fulfil the requirements for “Structural Glazing” or “VEC anodise”. The ink form of this inkjet printer is a permanent mark, which is difficult to remove.

Maintenance

Anodised aluminium used in architecture requires very little maintenance. The anodising layer consists of metal, aluminium oxide and is hard and robust. Maintenance is therefore understood to mean: cleaning of the product. A clean anodised aluminium surface has a very long lifespan. Under normal conditions, it can easily last 80 years, without losing its gloss or colour (e.g. the electrolytically dyed layers).

20 Or 40 year guarantee

Alumet B.V. hereby declares that the anodising activities that it has performed meet the QUALANOD requirements, class 20 mu or 25 mu, which Alumet B.V. and the client had agreed upon in writing. This means that the anodised components will be free of any corrosion and will not contain any cracks, blisters or filiform corrosion. Corrosion on the unprotected and untreated cut will not affect the adjacent anodising layers. The natural and electrolytically coloured components will also not be subject to any discolouration when exposed to sunlight.
